Chrome: Kill Evil is a simple extension that disables annoying scripts all across the web, like sites that won't let you right-click, sites that won't let you copy images, or sites that paste in citation links whenever you copy their text.

Most of these annoying tweaks run on JavaScript, and while you can disable all scripts with an extension like NoScript, you risk disabling JavaScript features you actually want. Kill Evil is a happy medium between the two: It lets JavaScript run on most pages, but disables some of the more popular annoyances people can add to their sites, including:

Every once in a while, it does get something wrong though, so if you find a page isn't working correctly, you'll still want to whitelist it in Kill Evil's preferences (many of the extension's reviews mention that you should whitelist most Google services, since they run a lot of JavaScript). That said, it's a great way to quickly get rid of some big web annoyances without blocking scripts altogether.
